BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is related to an improved inserting engaging frame for photos, and especially to a frame for photos in which a back plate on the back side of the frame body does not need to have its lateral and top edges provided with holes, thereby the frame is completely closed.

2. Description of the Prior Art

In a conventional inserting assembling or engaging type frame for photos, on which no small metallic accessories like screws or clasps etc. are required for assembling, a back plate is assembled on the back side of the frame body which has an opening area in coincidence with a photo size, a slide rail unit with slide channels is provided on the periphery of the opening area on the back side of the frame body, the slide rail unit has on its one end an entry/exit for sliding in and out of the back plate; the frame body and the back plate both are suitable for integrally injection molding in a mass production and economic mode. The back plate is formed on its back side pivotally connecting seats; and a bracing strut is connected to the pivotally connecting seats for bracing up the frame.

Such a conventional inserting assembling type frame is defective in that: a) Dirt can get in through holes provided on two lateral edges and a top edge of the opening of the frame, and the frame for photos is subjected to damaging; besides, the holes may destroy esthetic beauty of the entire frame. b) Assembling of the bracing strut is harder by having two lateral end protrusions to connect with the pivotally connecting seats and is subjected to inducing dropping off.

SUMMARY OF THE INVENTION

The present invention mainly provides improvement upon the prior art, it forms channels along the two lateral intact and none-hole edges of an opening on the back side of the frame body, and an intact and none-hole top edge is provided on a top rim of the opening; thereby a back plate for receiving photos can allow its two lateral sides to slide in the channels, so that the photos to be displayed can be placed in the opening of the frame body. Moreover, an engaging recess is provided only at the bottom edge on the opening on the back side of the frame body to match a protruding engaging rib provided on the bottom edge of the back plate; after assembling of the back plate on the frame body, the engaging rib engages in position in the engaging recess, thereby the back plate will not slide and drop.

Hence the primary object of the present invention is to provide an improved inserting engaging frame for photos, wherein the back side of the frame body has a totally closed and sealed back plate that can prevent dirt from getting in through the holes, and can get an effect of firm assembling.

A further object of the present invention is to provide an improved inserting engaging frame for photos, wherein the pivotally connecting seats formed on the back side of the back plate are designed to be arciform sheet members with their middle sections opened; a bracing strut is provided on its top with a rotating axle, it needs only to press the rotating axle into pivotally connecting seats, and assembling work can be completed, such assembling is fast and firm.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 and 2, same as the above stated prior art, the present invention has a frame body 10, a back plate 20 for receiving photos and a bracing strut 30 with a supporting function.

The frame body 10 has an opening 11 in the central area of it, the opening 11 can be provided thereon with a transparent member such as of glass or acrylic etc. The back side of the frame body 10 is provided on the two lateral rims of the opening 11 with L shaped lateral edges 12 which are intact without any hole and form channels 13; the back side of the frame body 10 is provided on the top rim of the opening 11 with a top edge 14 which is similarly intact without any hole. The back side of the frame body 10 is provided on the bottom rim of the opening 11 with an engaging recess 15.

The front side of the back plate 20 is used to receive and display photos, it has an area slightly larger than that of the opening 11, so that the two lateral sides of the back plate 20 can slide in along the channels 13 on the back side of the frame body 10 up to the top to contact the top edge 14 of the frame body 10 to completely seal the opening 11 as is shown in FIG. 3. The bottom edge of the back plate 20 has a protruding engaging rib 21 in correspondence by shape with the engaging recess 15 of the frame body 10, so that when the back plate 20 is assembled on the rear of the opening 11 of the frame body 10, the engaging rib 21 is exactly engaged in the engaging recess 15 as is shown in FIG. 4, thus the back plate 20 will not slide and drop off the channels 13. The back side of the back plate 20 has a pair of pivotally connecting seats 22 protruding outwards, each pivotally connecting seat 22 is an arciform sheet member with its middle section opened to pivotally connect with the bracing strut 30.

The bracing strut 30 is an elongate sheet member, it is provided on its top with a rotating axle 31; the diameter of the rotating axle 31 is about that of the arciform sheet member of the pivotally connecting seats 22 but larger than the opened middle section for pivotally connecting the bracing strut 30, so that the rotating axle 31 can be forcedly pressed into the pivotally connecting seats 22 without dropping, and the bracing strut 30 can be rotated about the pivot. FIG. 4 is depicted that the bracing strut 30 is rotated outwards for an angle to brace up the frame body 10 and the back plate 20; FIG. 5 is depicted that the bracing strut 30 is collapsed to be parallel to the frame body 10 in favor of storing.

On thing is worth mentioning, the present invention takes advantage of engaging of the engaging recess 15 of the frame body 10 with the protruding engaging rib 21 of the back plate 20 to complete assembling and positioning of the back plate 20 on the back side of the frame body 10; there is no hole on the lateral edges 12 or the top edge 14, thus the assembling is in a completely closed state, this not only can prevent dirt from getting in, but also makes the action of assembling by engaging of only the engaging recess 15 with engaging rib 21 (one edge) of the present invention easier and firmer than that of the prior art using engaging of three points.

And more, the improvement on the pivotally connecting seats 22 of the back plate 20 is the arciform sheet members with their middle sections opened, in cooperation with the rotating axle 31 of the bracing strut 30, the present invention needs only to press the rotating axle 31 into the pivotally connecting seats 22 and thus is simpler and faster in assembling structurally than the prior art; and is firmer by virtue that the contact area in assembling of the present invention is larger.

Further referring to FIG. 6 depicting the back plate 20 in a sectional view, a recess 23 is formed on the front side of the back plate 20 for receiving photos to be displayed.

Referring to FIG. 7 depicting the pair of pivotally connecting seats 22 of the back plate 20 and the rotating axle 31 of the bracing strut 30, wherein the pivotally connecting seats 22 are arciform sheet members 221 with middle openings 222; the width of each middle opening 222 is slightly smaller than the diameter of the of the rotating axle 31 of the bracing strut 30, thereby the rotating axle 31 can be forcedly pressed into the pivotally connecting seats 22 without dropping. The pivotally connecting seats 22 each is provided on its outer lateral sides with two plane plates 223 to limit the rotating axle 31 to rotate within the space formed by the two plane plates 223. And the rotating axle 31 of the bracing strut 30 is formed thereabove an abutting block 32, the abutting block 32 can be used to abut against an inner edge 24 of the back plate 20 to limit the stretching angular range of the frame body 10 when the bracing strut 30 is rotated outwards relatively to the frame body 10, and the frame can be assured to firmly stand.
